The Osmo system from DJI combines the Zenmuse X3 camera/gimbal with a detachable handle, bringing the benefits of stabilized 4K shooting to a handheld form factor. It enables up to full DCI 4K (4096 x 2160) video recording at 24 or 25p with MP4 format in a MOV wrapper (MPEG-4 AVC/H.264). 4K videos enables a really wide variety of operational possibilities for content material production. However, when you try to import DJI Osmo 4K recordings to CyberLink PowerDirector on Mac for further editing, you will encounter problems:

"I've tried to get some 4K MP4 footage from DJI Osmo to work in CyberLink PowerDirector on El Capitan. It imports, but when I try to do anything with it, it crashes. What's the problem?"

Solution: Till now, CyberLink PowerDirector cannot deal with 4K files perfectly. Therefore, in order to edit DJI Osmo 4K footages in CyberLink PowerDirector losslessly, you have to convert 4K video to CyberLink PowerDirector compatible MPEG-2 .mpg formats in advance via aPubsoft HD Video Converter for Mac, a professional yet easy-to-use tool to help users make the 4K video to MPEG-2 trancoding on Mac.

Once the DJI Osmo 4K video to MPEG-2 conversion finished, you can click "Open Folder" button to get the generated MPEG-2 .mpg files and transfer them into CyberLink PowerDirector for editing on Mac OS(Sierra, El Capitan, etc) without any issue.
